Hi

I want to create a trigger that copies a text column datatype from one database to another database in a specific text column.

to be more precise I use a trigger in one database , and when an insert happens I want to copy the text column in the other database

How I do it ?

Something like this, perhaps:


CREATE TRIGGER tg_MoveText
ON YourTable
FOR INSERT 
AS
BEGIN
  IF @@ROWCOUNT = 0 
    RETURN

  INSERT YourOtherDB..YourOtherTable (YourTextCol, YourPK)
  SELECT YourTextCol, YourPK
  FROM INSERTED
END

I forget the circumstances, but I don't think a text column is available, for this type of job, from INSERTED unless you do an INSTEAD OF TRIGGER is it?

But there again I may just be barking ....

Nope, I just tested and you're completely correct...

However, this does work:

use tempdb
go

create table blah (blah1 text, pk int)
go

create trigger tg_blah
on blah
for insert as
begin
select blah1
from blah
where pk in
(select pk
from inserted)
end
go

insert blah values ('blah', 1)
go

drop trigger tg_blah
drop table blah
go
